TOOL OR TOOLS FOR EARTHWORKING IMPLEMENTS.

Specification of Letters Patent.

Patented Feb. 25, 1913.

Original application flied January 2, 1908, Serial No. 409,034. Divided and this application filed March 9, 1909. Serial No. 482,311.

To all whom, it may concern Be it known that I, CIIARLS P. A. Farneao, a citizen of the United States, residing at Holinc in the county of Rock Island and State of lllinois, have invented certain new and useful Improvements in Tool or Tools for Earthworking Implements, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to earth working tools such, for example, as are employed in connection with CHlt-lVtltOlS.

The object of the invention is to provide improved devices for adjustably supporting the tools.

It will be understood from the description which follows that some, at least, of my improvements are applicable to tools of various forms. This application is a division of my earlier application for cultivators, filed Jan. 2, 1008, Ser. No. 409,034, and I have accordingly shown my invention only as applied to the disk form of tools shown in said earlier application.

In the drawings-l*igure 1 is a plan view of a pair of tool gangs and parts of a cultivator with which they are more or less directly associated. Fig. 2 is a side elevation of the parts shown in Fig. 1. Fig. 8 is a vertical section of the parts which carry and support a tool gang. Figs. 4. l"), 6, 7 and 8 show, detached, some of the detail nirts illustrated in Fi 8, the sections of Figs. I) and 7 being taken on the line 5-5 and 7-7, respectively, of Fig. t-l. Fig. 0 is a rear elevation of one of the tool gan s. Fig. 10 is a plan view of the parts siown in Fig. 0.

Referring in detail to the construction shown, 1 indicates a portion of the rigid wheel frame of a cultivator, such as is shown in my earlier application referred to above.

2 are drug bars flexibly connected at their front ends, preferably by ball and socket joints 3. 3, to the said wheel frame.

4, 4 designate as entireties two gangs of tools connected with the lower rear ends of the drag bars.

5 is a distance bar disposed between the two gangs of tools for the purpose of maintaining them in proper relation to each other.

My present invention relates more especially to devices by which the tools are carried and supported. These parts are arranged and constructed as follows: 29 indicates a box-like part having the lower element or half 30, and the upper element 31. These are formed with a chamber of such character as to accommodate a journal-like part 34, to be fitted therein. The upper and lower elements or halves 80, 31, are secured together by cars 32 and bolts 33. The lower part 30 has forward projecting bars or extensions 30 between which the drag bar 2 is secured. The said parts 30 and 81 are so shaped as to provide, when they are secured together, an annular chamber or recess 30 into which is fitted a flange 31" on the end of the journal part 34. This part 34 can be rotated more or less on a horizontal axis in the box structure provided by the parts described and can be fastened in any of several positions.

35 is a plate secured ri idly to the upper element of the box and having tapered or wedge-shaped lock teeth 36 with their thinner edges extending downward.

87 is an arm or bar carried by the journal element 34 and it sup )orts a rock shaft 80. The latter carries wedge-shaped detents 88 adapted to be engaged with and disengaged from the teeth 30. These detents 38 have their thinner edges extending upward and their ends are beveled or eccentrieally rounded so as to secure a continuous or camlikc engagement with the sides of the teeth 30, when the detents are moved into locking position. The rock shaft 30 has a lag 41 at one end, to which a saring is attached which tends to hold tie detents 38 in engagement with the teeth 30, and by reason of the wedge shape of said detents and teeth, the disk carrier is held firmly in adjusted position without play. The rockshaft 30 has a handle 42 by which it can be readily turned sulliciently to disengage the detent when adjustmentis to be made. The bar 5 by which the two gangs are connected is arched centrally to pass over the plants of a row and has its ends extending laterally and horizontally. To these horizontally extending end sections of the bar the box structures just described are clamped in the manner shown.

44 is a clamp block adapted to be mounted in a seat at 40 in the top of the box ele- BEST AVAlLABLE cos ment 31. 45 is a clampin bolt by which this block 44 can be forced tightly downward u )on the end of the arch-bar 5.

The ournal part 34 above referred to is one section of the supporting bar or plate from which extend downward the devices that carry the tools. The supporting bar or plate referred to is indicated as an entirety )y 47. At 48, 49 it is formed with a bearing for a vertically arran ed journal element to be described. Preferably it is cast hollow so that it can be made s'ufiiciently large and at the same time be light. The bearings at 48, 49 are preferably tapered apertures, that at 48 being somew iat larger in diameter'than that at 49. The rear part or extension of this supporting bar or plate is indicated by 50. At its outer end it has a series of wedge-shaped lockin teeth 51.

The carrier for the tools is indicated as a whole by 59. and is formed with an upper part 53 and a lower art 54. The upper part 53 is formed wit 1 a journal section which is seated in the bearings at 48, 49, and is preferably coned or tapered somewhat as shown in Fig. 3. RCtllWill'd from this there extends an upwardly turned plate or arm 57 which lies below the plate 50. At its rear end it has a handle 58 connected to the nut 57 by a curved or inclined section 59. On the parts 58, 59 there is mounted a detcnt lever having wcd e-sha ed detents 62 and a handle 63, these eing ield by a pivot 01. At (54 there is a spring bearing against the detent end of the lever and tending to hold the inclined faces of the detents in engagement with the correspondingly inclined faces of the teeth 51 on the plate 50. Whenever the operator desires to ad'ust the cultivator tools around the vertical axis he gras s the handles 58 and (33 and draws upwar on the latter. This releases the detent (v2 from the teeth 51 and unlocks the disk carrier. TllCIQUPOll he can swing the arts 58 and 57 and with them the disk carrier to the right or to the left as desired, and upon releasing the handle (33, the spring 64 insures its being tightly locked in the position of new ad ustment.

The iower part 54 of the carrier has laterally extending arms and to these are secured the suspending arms or bars 56. The latter, together with the part 54 and the upper part 53 of the hanger are secured rigidly together by the clam bolt 65, the head 68 of which lies under tie suspending device 56, and which is provided with a clamping nut at its 11 er end.

67 is a washer whic receives the thrust when the above mentioned parts are drawn upward by the bolt.

Under some circumstances, it is desirable to invert the gang of tools, that is, turn them end for end, as shown in Figs. 9 and 10, so

that the disk will throw the earth outward l bar,

instead of inward. This is here provided for by forming the engaging surfaces of the upper part 53 and lower part 54 of the carrier in the way shown in Figs. 3 and 7. G8 are lugs formed on the lower surface of the upper part 53, and 69 are lugs formed on the upper face of the lower part 54. To invert or turn end for end the lower part ofthe disk hanger it is only necessary to loosen the nut on the bolt (35 sufficiently to permit the lugs (38 and 69 to drop out of engagement, whereupon the inverting of the gang is permitted. After it has been turned halfway around, the nut and bolt are again drawn tightly to place.

The lower ends 70 of the sus )ending devices 56 are secured to hearing oxes 71 in which the gang of disks 86 are mounted in any preferred or suitable manner.

The operator has control of the positions of the gangs, to some extent, through the foot-bars 89 and the stirrups 90 rising from the plate 50. Each bar and support can be adjusted by means of a rose-plate connection at 91, the opposing elements of the adjusting device being secured together by a bolt at 92.

Scrapers are supported by the parts shown at 93, these being bars secured in seats or sockets formed on the lower part 54 of the disk carrier and being readily adjustable therewith to any position taken by the ang. These scraper supmrting bars can be withdrawn when desired and inverted, as will be necessary when the disk gang is turned end for end in the way above described.

It will, of course. be understood that when a tool gum is used on a cultivator, suitable means wifi be employed for raising and lowering it and for adjustubly suspending it, so as to work the earth to the desired depth, this vertical adjustment supplementing the other adjustments of the gang which have been described. It is obvious also that the gangs may be adjusted toward or from each other and maintained in such adjusted 70Slil0ll by the bar 5.
